To calculate combinations we use the nCr formula: nCr = n! / r! * (n - r)!, where n = number of items, and r = number of items being chosen at a time.
What is nCr probability?
In probability, nCr states the selection of 'r' elements from a group or set of 'n' elements, such that the order of elements does not matter. The formula to find combinations of elements is: nCr = n!/[r!(
How do you calculate C in a combination?
- #include <stdio.h>
- int fact(int);
- void main() {
- int n,r,ncr;
- printf("Enter a number n\n"); scanf("%d",&n);
- printf("Enter a number r\n"); scanf("%d",&r);
- ncr=fact(n)/(fact(r)*fact(n-r)); printf("Value of %dC%d = %d\n",n,r,ncr);
- }
